Condom broke a a couple days before my period..and im almost a week late. Help?

My boyfriend and I were having sex a day or two before I was expecting my period to show. Before he had ejaculated he noticed the condom felt weird, looked and it was completely broken. He said there was probably precum but he was almost done so he wiped off his penis and we went on without a condom and pulled out. The only thing that's keeping me from freaking out is that I'm not very regular to begin with. Every once in a while I'll have several consecutive months where my mentral cycle is on time, especially as I'm getting older (21 yrs old). Last month in October I got it on the 15th and I haven't got my period yet and its November 19th. I don't know if its just my irregular schedule or if I could be pregnant. A few women told me to get a test, that it won't hurt. But I'm a little skeptical, will they be accurate if I take the test now, or is it to soon? Any ideas or advice?? Thanks a lot!!
